That's why shipping axolotl cost so much to begin with . I ship my axolotl using high grade insulation material insulated box that I hand made, and shipping cooling packs. For bigger box you can buy premake insulated box online they comes with foam cooler or foam blocked wall then I just added double bubble foil insulated liner ( industrial made for cold and radio heat protection) and added enough ice gel packs ( made for shipping) that will keep package cool till their destination . The main thing is to use express shipping service only!
Express Shipping will delivery next day, or the day after next for further destination . You can NEVER skim on insulated material. Also I'm using protecting labels which you can get for like "
Live Fish please handle with care" or "
perishable please handle with care" and the arrows sigh that point upward for correct box position. Plus I buy breather bags only.
Shipping express by air around US rate from $ 35-45 per axolotl ( only same state can be $25)
Buying Shipping materials complete cost per box rate from $10-12 per axolotl ( complete hand made from scratch cost like $4-6 per a single complete box.)
Breather bag cost somewhere between a dollar.
Plus it's seller responsibility to 100% guarantee live arrival or money back or free replacement axolotl
